No audio device installed - Acer Aspire 4315 Notebook

hello jenz8860, try open device manager (run type devmgmt.msc), if u find question mark on your audio device then u need to install audio driver.
to install audio driver use motherboard driver, insert to CDROM, right click the audio device on device manager then update driver. choose recommended option then click next and follow the instruction. your audio device will automatically installed. if it success installed then u need to restart your PC.
if there is no problem in device manager, high possibility it's on hardware problem, try to see cable connection between speaker and PC (use back panel connection, don't use front panel audio, this to make sure the connection is good), if it's ok then mostly problem came from your speaker. try to use another speaker.
hope this useful, regards.

Dear wayne_intila:

Any device you are going to use can be installed if you have installer such as c-media. Or you can use Colossus Hi-fi Speakers for computer. You can download free installer for audio device. Just click here http://download.cnet.com/C-Media-AC97-Audio-Device/3000-2120_4-154785.html copy this link and paste it to address bar and enter then download. Plug the audio device before you install.

i think this problem come from your audio driver, check at device manager?is there any yellow mark at device manager?if yes it mean your audio driver not installed
inserd your motherboard cd driver, then install audio driver
another way is from device manager, rihgt click at yellow mark, chose update driver, then follow instruction step by step with motherboard cd driver insertted at cd rom, wait until installation finish and at device manager the yellow mark disappear

after installation try to mplay music

i hope this helpful
thank you for using fixya

First check the device manager from the control panel. Check and see if there is a audio device detected and if it is a problem device.If the device has a problem try removing the audio software and then remove the audio device.then re-boot the computer and windows should detect the hardware and begin installing drivers. Make sure you have the updated drivers from Dell downloaded and the updated software. If it does not detect the hardware after re-boot you can try adding hardware manually in the control panel and have it auto detect any new hardware. If these thins do not work the audio card or built in audio may have stopped working. You can buy a basic PCI audio car for fairly cheap to install on your computer if you cannot get the audio to work.

I would try the realtek audio driver instead. there are two different audio drivers for that board. Here is the link:

select the socket 775 then look for the p5kpl board then look in the audio section and select the realtek driver

Do you have windows XP or Vista?
Do you have sigmatell audio card?

When this happens go to start->run type in services.msc and press run.
Find Windows audio service. Right click and select properties. SElect start type "automatic" and click on start.
Audio should work.
Please leave your feedback if issue was solved or if you still have that problem

i think u already installed audio device first remove that after then install your new audio device and enjoy your high definition audio bus

i cant install the audio device driver

You probably need Microsoft UAA drivers first
1) Remove any installed audio drivers through device manager
2) Download Microsoft UAA drivers for your O/S
3) Install them and reboot
4) go to device manager right click sound and update driver
It will go on the net and in most cases find and install them

have installed XP in Compaq Presario 707TU Laptop. I have configured audio as below. Install Microsoft UAA sp31994, then install High-definition audio driver sp33443. But I get the error message "Driver Installation Failed: Could not find the MEDIA device for this driver."...
